CORPORATION OF NEW YORK CENTRIFUGAL EXTRACTOR Application filed April 8, i926. Serial No. 100,580.

lThis invention relates to centrifugal extractors a-nd the likehand aims toprovide means for causing a liquid to move radially outward through a wound `mass of yarn.

A particular object ofthe invention is to extract liquid from wound masses of yarn,

such as cones of yarn. According to the in-v4 vention, an individual wound mass or cone is rotated rapidly about its axis in a holder which, while permitting the centrifugal force to extract any liquid contained in the mass, prevents this force from disrupting the mass or displacing the yarn. Furthermore, the holder is so arranged that a cone of yarn may quickly and easily be inserted therein or removed therefrom, thus facilitating rapid operation of the extractor.

Other objects and advantages of the invention arev hereinafter explained in connection with a detailed description of a specific device embodying the invention which is shown in the accompanying drawings, in which Fig. 1 is a side elevation partly in axial section; and

. Fig. 2 is an end elevation with parts broken away. f

The device shown in the drawing has a frame or table 10 on which are mounted two standards 11, 11 containing bearings in which a short shaft 12 is rotatably mounted. Between the standards 11, 11 means are provided for rotating the shaft l2 rapidly, for example, at 2000 R. P. M. or more. In the form illustrated, suchmeans include a belt pulley 13 fixed on the central portion of the shaft and a beltlllrunning over this pulley and driven from a larger power-driven puli ley located below the table 10 and not shown in the drawings. On the opposite ends of the shaft 12 are mounted yarn holders 15, 15. Each yarn holder is formed to engage thev outer surface of a mass of yarn all the way about its circumference and to hold the mass with its axis coincident with that of the shaft 12. The holders are provided with perforations 16, or otherwise made foraminous, to4 permit the passage of liquid extracted from the masses of yarn. v

Each of the holders illustrated has the form of a frustum of a cone closed and mounted on the shaft 12 at its smaller'end and open at its larger outer end. A cone of yarn, that is, a frusto-conical mass of yarn C wound on a conical core C1, may beinserted through the larger end of one of the holders, and,

when pushed inward, is firmly engaged by a casing 17. Each casing is closed at its inner end by an end wall 18 containing a central hole to permit the passage of one end of the shaft 12. The outer end wall 19 of each casing contains a large central opening 20, as large or larger than the outer end of the holder 15, or 15', to facilitate the insertion andthe removal of cones of yarn. As no liquid is thrown in an axial direction, all theliquid thrown off from the cones is caught in the casings and may be removed through drain pipes 2 1 extending from the bottoms of the casings.,v

The operation of the device is obvious Q from the foregoing description.

Among the advantages ofthe device it should be noted that a very ra id and thorough extraction may be obtained' by rotating the shaft at high velocity because of the fact that the cones of. yarn are held and f rotated by means engaging their outer surfaces so that the cones cannot be deformed or disrupted by the centrifugal force. The yarn may be inserted in the usual form in which it is wound so that no `special winding or arrangement of the yarn is necessary in preparing it for extraction.

The liquid in each cone of'yarn is thrown directly radially y outward so that the device is applicable to the extraction of liquid from partially dyed cones aswell as completely dyed cones. Fur; theremore, if in the dyeing or other treatment of the yarn the paper core on which 'it is A wound hasbecome saturated with liquid and thus softened vor misshapen, the corev is reystored to its normal shape by the centrifugal force which urges it outward against the yarn and dries and stiffens in its normal shape.

.While-the device which has been described Y is intended primarily as an extractor, it may also be used for other purposes, for example, in carrying out a method of dyeing invented by Henry E. Van Ness and describedand claimed in his application filed March 11, 1926, Serial No. 93,821. We wish it understood, therefore, that our invention is not limited to any particular use ofthe device described, andlthat it covers any modifications ther'eo'fwhich are within the claims that follow. f f' What is claimed is:

I1. A.. device for extracting Aliquid from yarn wound in the form'of yarn cones, comprising a rigid foraminuous frusto-conical holder having substantially the same taper as the yar-n cones,`longer than the yarn cones,

and open at its larger end to receive 'one of the yarn cones, and means secured to the holder-.for rapidly rotating it and a yarn cone wedged into it about the axis of the yarn cone.

2. Apparatus for extracting liquid from yarn wound in a mass of predetermined form, comprising the combination with means for rotating the mass about its axis, of a foraminous ooniner formed to fit tightly against the peripheral surface of the mass to prevent disruption of the mass by cntrifugalfprce.

3. In apparatus ofthe class described, the combination with spaced bearings and a shaft rotatably mounted thereon, of oraminous yarn holders secured to opposite ends of the shaft outside said bearings, and means engaging the shaft between said bearings for rotating it.- t

In testimony whereof we havell hereunto set our hands. 'l JOHNP. GAREY. 2
